Problem after Head install
Just put on a set of Texas speed heads on my 05 5.3. When i started it, it sounds like its missing, and wont hardly run. Engine idles real rough. Check engine light came on, scanned said it was PO101. Can anyone help?

That's a mass airflow code.Was it just a head swap?Did you change cam as well?Might need a tune.

sure you don't have the maf unplugged? Check for loose hoses too.
